People who live in Creationist houses should not throw methodological stones. - Philip Kitcher

Creation “science” is spurious science. To treat it as science we would have to overlook its intolerable vagueness. We would have to abandon large parts of well-established sciences (physics, chemistry, and geology, as well as evolutionary biology, are all candidates for revision). We would have to trade careful technical procedures for blind guesses, unified theories for motley collections of special techniques. Exceptional cases, whose careful pursuit has so often led to important turnings in the history of science, would be dismissed with a wave of the hand. Nor would there be any gains. There is not a single scientific question to which Creationism provides its own detailed problem solution. In short, Creationism could take a place among the sciences only if the substance and methods of contemporary science were mutilated to make room for a scientifically worthless doctrine. What price Creationism?

This is purely a figment of Gish’s imagination. He speculates about the character of transitional forms, and then chides paleontologists because they do not find what he demands.

To provide scientific explanations, a creationist would have to identify the plan implemented in the creation. The trouble is that there are countless examples of properties of organisms that are hard to integrate into a coherent theory of design. There are two main types of difficulty, stemming from the frequent tinkerings of evolution in the equally common nastiness of nature. Let us begin with evolutionary tinkering. Structures already present or modified to answer to the organisms current needs. The result may be clumsy and inefficient, but it gets the job done.… (examples of the panda’s thumb, orchid self-fertilization, and the ruminant digestive system elided)
The second class of cases cover those in which, to put it bluntly, nature’s ways are rather repulsive. There is nothing intrinsically beautiful about the scavenging of vultures, the copulatory behavior of the female praying mantis (who tries to bite off the head of the “lucky” male), or the ways in which some insects paralyze their prey.… (example of coprophagy elided)
